Question

Given an array of positive integers, determine whether it can be partitioned into two subsets with equal sum. Return true if such a partition exists, otherwise false. Constraints: 1 <= n <= 200, 1 <= nums[i] <= 100.

Implement
can_partition(nums: list[int]) → bool
Examples
in[[1,5,11,5]]outtrue
What a strong answer looks like

State your approach and its time/space complexity out loud before you optimize. Handle the edge cases (empty input, duplicates, overflow), and say why you chose this over the brute force. Green tests are the floor, not the grade.

Vibe coding: describe the solution in plain language (or narrate it) and the coach grades your approach. Generating runnable code from your description is coming next.

Run or narrate your approach, then ask the coach.
